Thanks for the replies, I will check out the Samuri course in a bit more detail.

In regards to the Blacklight course the only thing that puts me off is I have done Encase 2 and Advanced and I only really want to focus on Mac computers rather than Windows. I can't see a time where I would ever use Blacklight over Encase/FTK/Netclean to conduct Windows based investigation.

I will have to find out how much Windows based content there is and go from there.
